Abstract

In some examples, a tunable dense wavelength division multiplexing (DWDM) optical time domain reflectometer (OTDR) may include a fiber optic link analyzer, executed by at least one hardware processor, to tune a test wavelength of the DWDM OTDR to an effective wavelength of DWDM channels. A non-temperature compensated multiplexer/demultiplexer (Mux/DeMux) located at a distant location, collocated with, or embedded within the DWDM OTDR may selectively connect, based on the test wavelength, the DWDM OTDR to a fiber optic link of a plurality of fiber optic links to test the fiber optic link. A reflective device may be connected to an output of the Mux/DeMux to provide a reference for setting the test wavelength of the DWDM OTDR on a selected channel of the Mux/DeMux.
